I'm trying to become greener and print less invoices.
 
This may not apply to businesses that are exclusively online shop. the rest will understand my request and why it needs to be done.
 
My request is to be able to upload pdf invoices created outside of the cart software to replace the existing cart generated invoices.
 
There are two main reasons this is necessary,
 
1) Online shop order numbers are NOT the same as as invoice numbers.
2) Accounting software like MYOB is where all the financial references will always be in my business. All sales I ever do will go through this software so it makes sense that a customer can download the REAL INVOICE and not a cart generated order. Then after applying an order status I can email the correct official invoice to the customer while only printing a packing slip at time of delivery.
 
What they say? Is this somethign you'll all want?
 
Now this is not something i would imagine to be hard to achieve.
